Don't underestimate the three hazards of chemical fertilizers!

Don't underestimate the three hazards of chemical fertilizers!

Chemical fertilizers are indispensable in agricultural production. However, it has three major hazards that hinder the development and progress of agriculture.

A major hazard: the physical properties of the soil are destroyed

Soil physical properties are destroyed. What are the serious consequences? Let’s first look at what soil physical properties are: soil physical properties include soil structure and porosity, soil moisture, soil air, soil heat, and soil cultivability, etc. . Among them, soil moisture, air and heat as the constituent elements of soil fertility directly affect the fertility status of the soil, and the rest of the physical properties restrict the activity of soil microorganisms and the transformation and existence of mineral nutrients by affecting the status of soil moisture, air and heat. And its supply, etc., in turn have an indirect impact on soil fertility. Learning and mastering the basic theories of soil physical properties and their control measures are of great significance for continuous soil fertility, improvement of soil productivity, and realization of the sustainable use of soil resources.

In other words, the physical properties of the soil are destroyed, which will cause defertilization. Even if the fertilizer is used more, the crops will grow vigorously because there is no suitable growth environment.

The second major hazard: soil acidification

my country has a vast territory, the terrain is even more complex and changeable, and the pH of the soil does not have a fixed value. After scientific investigation, it has been found that the most suitable soil pH for crop growth is between 6.5 and 7.5.

The effects of soil acidification on crops are as follows:

1. The root system does not grow

2. Decreased fertility

3. Activities affecting soil microorganisms

4. Cause pollution

The third major hazard: soil compaction

Extensive use of chemical fertilizers will affect the permeability of the soil and have certain effects on the respiration of plants. If the roots of crops cannot ensure normal respiration, it will cause root necrosis and inability to absorb nutrients, resulting in reduced production.

It is imperative to reduce the amount of fertilizer. Protect the soil, protect the agriculture, start with me, start with halving the fertilizer!
